This type of packaging container is composed of, for example, a cylindrical outer box and an open inner box that is inserted into the outer box, and the opening and closing operations are performed by making the inner box slidable with respect to the outer box. It is like this. At the time of packaging, the products that are stored in the inner boxes are inserted into the outer boxes, and tapes are attached to prevent the boxes from slipping.

[0003]

[Problems to be solved by the device]

 However, according to such a conventional packaging container, when the packaged product is displayed for a long period of time, the tape or the like for stopping each box may come off, and the stored product is likely to come out of the container. For example, when a packaging container is hung on an exhibition stand or the like for display, if the tape, etc. comes off, the inner box will slide downward due to the weight of the stored item, and the inner box will fall out of the display stage and the stored item will fall. There is a fear. In such a case, the outer box and the inner box can be fixed again with tape or the like, but the work is complicated, and the container is often scratched and dirty.

The present invention has been made in order to solve such a problem. The outer box and the inner box can be opened and closed by a sliding operation to facilitate the packaging work, and at the time of exhibition, storage, etc. Another object of the present invention is to provide a packaging container that prevents the stored items from being opened to the outside due to the deviation of the outer and inner boxes.

[0005]

[Means for Solving Problems]

 Therefore, the packaging container of the present invention is a packaging container that has an outer box and an inner box made of a flexible plastic material, and slidably accommodates the inner box in a cylindrical hole of the outer box. A projection is provided at a predetermined position on the sliding surface of the inner box, and a fitting hole that can be fitted into the projection when the inner box is stored is provided on the cylindrical surface of the outer box. The cross-section of the cylindrical hole of the outer box is formed in an elliptical shape or a tree leaf shape. It is characterized in that a tongue plate is formed at an end portion of the inner box in the sliding direction, and a hooking hole is formed in the tongue plate. The plastic material is polyethylene terephthalate.

[0006]

[Action]

 According to the packaging container of the present invention, at the time of storage, the stored items are put in the inner box, and the inner box is inserted into the cylindrical hole of the outer box and slid. At this time, the sliding surface of the inner box is bent so that the projection slides in the cylindrical hole. When the protrusion fits into the fitting hole, the outer box and the inner box are locked. When the inner box is slid with the projection pushed into the inner side of the inner box when released, the sliding surface of the inner box bends and the projection comes out of the fitting hole. After sliding the inner box out from the outer box sufficiently, take out the stored items from the inner box. The opening / closing operation can be easily repeated any number of times.

Examples of the plastic material include polyethylene terephthalate (PET), polystyrene, biaxially oriented polystyrene, vinyl chloride resin, amorphous polyethylene terephthalate, P.I. P-philia (polypropylene + inorganic substance) or the like can be used. Further, PET may be combined with non-crystalline nylon or the like to form a multilayer structure, or a plastic material obtained by mixing PET with glass fibers or the like may be used. Further, instead of the plastic material, it is possible to use paper material or wood.

As shown in FIG. 3, the outer box 2 has a tubular hole H whose cross section is formed into a tree-like shape, and the short portion shown in FIG. It bends in the radial direction. A circular fitting hole 5 is formed in the cylindrical surface 2a. The fitting hole 5 is formed on the central axis of the cylindrical surface 2a and at a position lowered by a predetermined length from the upper end of FIG. 3 toward the center. The outer diameter of the fitting hole 5 is, for example, about 5 to 10 mm. Regarding the method for manufacturing the outer box 2, for example, a plastic plate is cut into a rectangular shape, folding curves are provided at the middle portion and side end portions of the rectangular plate, and then the rectangular plate is bent along these folding curves to form one Glue the side edge of the to the other side edge. As a result, the plate surface is bent, and the cylindrical hole H is formed so as to have a cross section of a leaf shape.
